Helical-worm gearmotors

Their greatest strength is their running smoothness and their extremely low noise development. In a nutshell: With the S..DR.. helical-worm gearmotors you are choosing a powerful drive solution which you will hardly even hear.

Their cost-effectiveness is due to their simple design. The individual adjustment of torque and speed enables space-saving installation of our helical-worm gear units. Use S series helical-worm gear units as a cost-effective solution for meeting basic requirements in your machine or plant applications. The torque range extends from 92 Nm to 4,000 Nm. For the S..7p it is 105 Nm to 4300 Nm.

Adding an input-side helical gear stage makes it possible to achieve significantly higher efficiency than with conventional worm gear units. The linear power transmission makes these helical-worm gear units exceptionally smooth-running and low-noise. Why? The torque is transmitted via the worm shaft and the worm gear to the input shaft. In a process that reduces torque impulses and facilitates low noise levels.
